Here are our HealerCDs Healing Guides for Siege of Orgrimmar, the new raid tier added in 5.4. We will continue to update as new strats, comp specific tricks and tactics, as well as bug fixes or known bugs for healers.
Do note, these are NOT complete raid guides for these fights, we are expecting that you know the basic mechanics of the fight (the dungeon journal and Icy Veins are good resources). Instead, these guides are strictly healing raid guides with tips and tricks for healers (and raid leaders) with healing specific strats that make healing easier and stronger.
